认清现实，放弃幻想，准备斗争
一、借款人申请借款
1、需求描述
2、相关数据库表
二、具体步骤
step1：借款人点击“我要借款”
step2：展示借款信息填写页面
step3：借款人填写信息并提交
step4：展示等待审核页面
5、平台审核
6、显示审批结果
未通过
通过
一、获取借款额度
1、实现思路
（1）获取借款人积分
（2）根据积分获取借款额度，借款人每次借款不能超过借款额度
2、Controller
BorrowInfoController
@Api(tags = "借款信息") @RestController @RequestMapping("/api/core/borrowInfo") @Slf4j public class BorrowInfoController { @Resource private BorrowInfoService borrowInfoService; @ApiOperation("获取借款额度") @GetMapping("/auth/getBorrowAmount") public R getBorrowAmount(HttpServletRequest request) { String token = request.getHeader("token"); Long userId = JwtUtils.getUserId(token); BigDecimal borrowAmount = borrowInfoService.getBorrowAmount(userId); return R.ok().data("borrowAmount", borrowAmount); } }
2、Service
接口：BorrowInfoService
BigDecimal getBorrowAmount(Long userId);
实现：BorrowInfoServiceImpl
@Service public class BorrowInfoServiceImpl extends ServiceImpl<BorrowInfoMapper, BorrowInfo> implements BorrowInfoService { @Resource private UserInfoMapper userInfoMapper; @Resource private IntegralGradeMapper integralGradeMapper; @Override public BigDecimal getBorrowAmount(Long userId) { //获取用户积分 UserInfo userInfo = userInfoMapper.selectById(userId); Assert.notNull(userInfo, ResponseEnum.LOGIN_MOBILE_ERROR); Integer integral = userInfo.getIntegral(); //根据积分查询借款额度 QueryWrapper<IntegralGrade> queryWrapper = new QueryWrapper<>(); queryWrapper.le("integral_start", integral); queryWrapper.ge("integral_end", integral); IntegralGrade integralGradeConfig = integralGradeMapper.selectOne(queryWrapper); if(integralGradeConfig == null){ return new BigDecimal("0"); } return integralGradeConfig.getBorrowAmount(); } }
二、借款入口前端
pages/user/borrower.vue
<NuxtLink to="/user/apply" v-if="borrowerStatus === 2"> <el-button style="margin-top:20px;" type="success"> 我要借款 </el-button> </NuxtLink>
三、借款申请
1、页面
pages/user/apply.vue
2、获取下拉列表
methods中定义
//初始化下拉列表的数据 initSelected() { //还款方式列表 this.$axios .$get('/api/core/dict/findByDictCode/returnMethod') .then((response) => { this.returnMethodList = response.data.dictList }) //资金用途列表 this.$axios .$get('/api/core/dict/findByDictCode/moneyUse') .then((response) => { this.moneyUseList = response.data.dictList }) },
created中调用
created() { //初始化下拉列表 this.initSelected() },
3、获取借款额度
methods中定义
//获取借款额度 getBorrowAmount() { this.$axios .$get('/api/core/borrowInfo/auth/getBorrowAmount') .then((response) => { this.borrowAmount = response.data.borrowAmount }) },
created中调用
created() { //获取借款额度 this.getBorrowAmount() //初始化下拉列表 ...... },
4、判断借款额度
借款人每次借款不能超过借款额度
watch: { 'borrowInfo.amount'(value) { if (value > this.borrowAmount) { let _this = this this.$alert('您的借款额度不足！', { type: 'error', callback() { _this.borrowInfo.amount = _this.borrowAmount }, }) } }, },
